If this is not observed, sparking, bursting, fire or electric

shocks may result.

Do not recharge the battery in places which have high

humidity or outdoors.

Do not insert or remove the plugs while they are wet. If the

insides of the plugs are wet, dry them thoroughly before

inserting them.

<SM-BCR1: Battery Charger / SM-BCC1: Battery Charger Cord>

Be sure to hold the power cable by the power plug when

connecting and disconnecting the power plug from the

electrical outlet.

If you do not hold the power cable by the power plug,

fire or electric shocks may occur.

* If heat or acrid-smelling smoke is coming out from the

power plug.

* There may be a bad connection inside the power plug.

Do not overload the electrical outlet with appliances

beyond its rated capacity, and use only a 100 – 240 V AC

electrical outlet.

If the electrical outlet is overloaded by connecting too

many appliances using adapters, overheating resulting in

fire may occur.

Do not damage the power cord or power plug. (Do not

damage, process, forcibly bend, twist or pull them, bring

them near hot objects, place heavy objects on them or

bundle them tightly together.)

If they are used while damaged, fire, electric shocks or

short-circuits may occur.

Do not use the charger with commercially-available

electrical transformers designed for overseas use.

If this is not observed, they may damage the charger.

Always be sure to insert the power plug as far as it will

go.

If this is not observed, fire may occur.

<FC-6700: Front Chainwheel>

•

Before riding the bicycle, check the crank arms thoroughly to see if they contain any cracks. If the crank arms are cracked,

they may break and you may fall off the bicycle.

For Installation to the Bicycle, and Maintenance:

•

When the shifting switch is operated, the motor which drives the front derailleur will operate without stopping at the

shifting lever position. Always be sure to disconnect the battery before carrying out installation, otherwise your fingers may

become stuck.

<FC-6700: Front Chainwheel>

•

The two left crank arm mounting bolts should be tightened alternately in stages rather than each bolt being fully tightened

all at once. Use a torque wrench to check that the final tightening torques are within the range of 12 - 14 N·m. Furthermore,

after riding approximately 100 km (60 miles), use a torque wrench to re-check the tightening torques. It is also important to

periodically check the tightening torques. If the tightening torques are too weak or if the mounting bolts are not tightened

alternately in stages, the left crank arm may come off and the bicycle may fall over, and serious injury may occur as a result.

•

If the inner cover is not correctly installed, corrosion of the axle may occur, and this may damage the axle and the bicycle

may fall over, and serious injury may occur as a result.

<CN-6701: 10-speed Chain for Road Riding>

•

Maintenance interval depends on the usage and riding circumstances. Clean regularly the chain with an

appropriate chaincleaner. Never use alkali based or acid based solvents such as rust cleaners. If those solvent be

used chain might break and cause serious injury.

•

In order to obtain good gear shifting performance, applicable chains have a forward side and a reverse side, and

the sides are marked so that the chains will face the correct way when installed. The proper design performance

will be obtained when the chains are installed so that they face the correct way. If the chains are installed so

that they face the opposite way, they may come off and the bicycle may fall over and serious injury may occur

as a result.

Forward (outer side) Reverse (inner side)

The side with the marks shown in the illustration is the forward side (outer side).

•

Narrow-type chains must always be connected using reinforced connecting pins.

•

If the chain is connected by using connecting pins other than reinforced connecting pins, or by using reinforced connecting

pins or tools which are not suitable for the chain, the connecting force provided maybe insufficient, and the chain may break

or fly off.

•

After connecting the chain, be sure to feel the connection with your fingers to check that

both ends of the connecting pin and the surfaces of the links are flush with each other. (The

opposite end of the pin which has been broken off should feel as though it is projecting very

slightly.)

•

If the length of the chain needs to be readjusted for reasons such as changes to the sprocket configuration, cut the chain at

a place which is not connected by means of a reinforced connecting pin. If you cut the chain at a place which has been

connected using a reinforced connecting pin, it will damage the chain.

•

Use a TL-CN41 chain wear indicator (Y12152000) or a similar tool to check if the chain has become stretched or damaged. If

the chain has become stretched or damaged, it may break and the bicycle may fall over, so the chain should be replaced.

•

When readjusting the length of the chain, be sure to insert the reinforced connecting pin from the same side as the chain

cutter was inserted (the same direction as when the chain was cut).

•

Be careful not to let the cuffs of your clothes get caught in the chain while riding, otherwise you may fall off the bicycle.

CAUTION

Be sure to also inform users of the following:

<SM-BCR1: Battery Charger / SM-BCC1: Battery Charger Cord>

•

Disconnect the power plug from the electrical outlet before cleaning.

<SM-BTR1: Lithium Ion Battery>

•

Do not disassemble or break the battery. If this is not observed, there is the danger that fire or burns may result.

•

Do not heat the battery to temperatures which exceed 60°C (140°F). In addition, do not put the battery into fire. Follow the

instructions provided by the battery’s manufacturer.

•

Store the battery in a safe place away from the reach of infants and pets.

NOTE

Be sure to also inform users of the following:

•

Be sure to keep turning the crank during the lever operation.

•

Be careful not to get water into the terminal.

•

If gear shifting operations cannot be carried out smoothly, clean the front and rear derailleurs and lubricate any moving

parts.

•

You should periodically wash the chainrings in a neutral detergent. In addition, cleaning the chain with neutral detergent

and lubricating it can be an effective way of extending the useful life of the chainrings and the chain.

•

Do not use thinner or other solvents to clean any of the components. Such substances may damage the surfaces.

•

Do not clean the bicycle with a high-pressure washer. If water gets into any of the components, operating problems or

rusting may result.

•

Handle the components carefully, and avoid subjecting them to any strong shocks.

•

Contact the place of purchase for updates of the component software. The most up-to-date information is available on the

Shimano website.

•

Products are not guaranteed against natural wear and deterioration from normal use and aging.

•

For maximum performance we highly recommend Shimano lubricants and maintenance products.

<SM-BCR1: Battery Charger / SM-BCC1: Battery Charger Cord>

•

If not using the battery for long periods, remove it and store it away in a safe place.

•

Used batteries should be disposed of in accordance with local waste regulations. Alternatively, ask the place of purchase or a

bicycle dealer for disposal.

•

This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack

of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person

responsible for their safety.

•

Do not let children play near these items.

Information on disposal in countries other than the European Union

This symbol is only applicable within the EU.

Used electrical items (battery chargers and battery charger cords) should be disposed

of in accordance with local laws and regulations, or ask the place of purchase or a

bicycle dealer for disposal.

<SM-BTR1: Battery>

•

The battery is uncharged at the time of purchase. Before riding, be sure to charge the battery until it is fully charged.

•

When storing the battery away, remove the battery from the bicycle and install the terminal cover first.

•

If the battery is stored away while the battery charge is 50% or higher (the indicator is illuminated green), the battery will

last longer.

It is recommended that you check the condition of the battery about once every half a year.

•

If the battery is stored in cold locations, the performance of the battery may drop and the length of time that it can be used

may become shortened.

•

The battery is a consumable item. The battery will gradually lose its capacity for charging after repeated use and after time

has passed. If the length of time that the battery can be used becomes extremely short, it has probably reached the end of

its life, and so you will need to purchase a new battery.

•

The life of the battery will vary depending on factors such as the storage method, the usage conditions, the surrounding

environment and the characteristics of the individual battery pack.

•

The charging time is approximately 1.5 hours. (Note that the actual time will vary depending on the amount of charge

remaining in the battery.)

•

If the battery feels difficult to insert or remove, apply specified grease (DURA-ACE grease) to the part that touches the

O-ring at the side.

•

For the DURA-ACE (7970), the bicycle can be ridden for approximately 1000 km on a full charge. For the ULTEGRA (6770), the

riding distance will be shorter. (Approximately 30% less according to tests carried out by Shimano.)

•

Charging can be carried out at any time regardless of the amount of charge remaining. Always be sure to use the special

battery charger to charge the battery until it is fully recharged.

•

If the battery has become fully spent, charge it as soon as possible. If you leave the battery without charging it, it will cause

the battery to deteriorate.

•

If you will not be riding the bicycle for a long period, remove the battery from the bicycle and recharge it periodically. In

addition, take care not to let the battery become fully spent.

Information on disposal in countries other than the European Union

This symbol is only applicable within the EU.

Used batteries should be disposed of in accordance with local laws and

regulations, or ask the place of purchase or a bicycle dealer for disposal.

<ST-6770: Dual Control Lever>

•

Be sure to rotate the front chainwheel when carrying out any lever operations which are related to gear shifting.

<RD-6770: Rear Derailleur>

•

If the amount of looseness in the links is so great that adjustment is not possible, you should replace the derailleur.

•

Periodically clean the derailleur and lubricate all moving parts and pulleys.

•

If there is a large amount of play in the pulleys which causes worrying noise while riding, replace the pulleys.

For Installation to the Bicycle, and Maintenance:

•

Do not keep connecting and disconnecting the small waterproof connector. It may impair the function.

•

Be sure to attach dummy plugs to any unused terminals.

•

The units are designed to be fully waterproof to withstand wet weather riding conditions. However, do not deliberately

place them into water.

•

Always be sure to use the Shimano original tool TL-EW02 to remove the electric wires.

•

If the chain keeps coming off the sprockets during use, replace the sprockets and the chain.

•

Do not disassemble, otherwise operating problems will result.

•

The motors of the front derailleur and the rear derailleur cannot be repaired.

•

Contact Shimano for information regarding the shipment of the battery charger to South Korea and Malaysia.

<EW-SD50/EW-SD50-I: Electric Wires / SM-EWC2: Electric Wire Covers>

•

Secure the electric wires with cable ties so that they do not interfere with the chainrings, sprockets and tires.

•

The strength of the adhesive is fairly weak, to prevent the paint on the frame from being peeled off at the same time when

removing the electric wire cover for reasons such as replacing the electric wires. If the electric wire cover is peeled off,

replace it with a new one.

When removing the electric wire cover, do not peel it off too vigorously. If this is not observed, the paint on the frame will

peel off too.

•

Do not remove the wire holders which are attached to the built-in type electric wires (EW-SD50-I). The wire holders prevent

the electric wires from moving inside the frame.

<ST-6770: Dual Control Lever>

•

SW-R610 cannot be used with ST-6770 because the shape of its connector is different from that of E-TUBE.

•

Dummy plugs are installed at the time of shipment from the factory. Do not remove them except when necessary.

•

When routing the electric wires, take care to ensure that they do not interfere with the brake levers.

<RD-6770: Rear Derailleur>

•

Always be sure to adjust the top adjustment bolt and the low adjustment bolt according to the instructions given in the

adjustment section. If these bolts are not adjusted, the chain may become clamped between the spokes and the large

sprocket and the wheel may lock, or the chain may slip onto the small sprocket.

•

If gear shifting adjustment cannot be carried out, check the degree of parallelism at the rear end of the bicycle. Also check

if the cable is lubricated and if the outer casing is too long or too short.

•

The tension pulley has an arrow on it to indicate the direction of rotation. Install the tension pulley so that the arrow is

pointing clockwise when looking at the outer side of the derailleur.

<CN-6701: 10-speed Chain for Road Riding>

•

As illustrated in Fig. A, we strongly recommend to set the connecting pin in the hole of the outer link on the front side in

the direction of travel. The chain’s level of strength is enhanced compared to the method in Fig. B.

•

Place the chain into the chain cutting tool as shown in the illustration. If the chain is set incorrectly into the chain cutting

tool, it will break the positioning plate.

Be sure to also inform users of the following:

When the system fails to operate, the system may be recovered by resetting the system power.

After the battery is removed, about one minute is usually required for the system power to reset.

In the case of using SM-BTR1

Remove the battery from the battery mount. After about one minute, install the battery.

In the case of using SM-BTR2

Disconnect the plug from SM-BTR2. After about one minute, insert the plug.

When the product is reassembled or replaced, it is automatically recognized by the system to allow operation according to the

settings.

If the system does not operate after reassembly and replacement, follow the system power reset procedure above to check the

operation.

For Installation to the Bicycle, and Maintenance:

If the component configuration changes or malfunction is observed, use the E-TUBE PROJECT software to update the firmware of

each component to the latest version and perform a check again.

Also make sure that E-TUBE PROJECT software is the latest version. If the software is not the latest version, the component

compatibility or the product functions may not be sufficiently available.
